new deck from marleybone problems

the deck that i bought in marleybone is only letting me use the cards that come with my jewelry and my wand in battle. I equipped 30 cards plus treasure cards to my deck and i can't use any of them. This therefore makes me useless in the game for battles and other things. What should i do to get my deck working?

Make sure you have your new deck equipped. Open your backpack when you're not in a duel by pressing B on your keyboard. Navigate to the tab with your decks and make sure the one you want to use has a hand icon beside it.

To equip it, double click on the deck.

Keep in mind you can cycle through your decks by pressing Ctrl-K on your keyboard.

well if quest tracker doesn't work when ya first click on a quest, don't type or anything just press ty. Idk why it works but it always brings quest tracker up unless it'a quest like for example "Find The Smiths".
